Be nice kids.

First of all, and I have to say this because of some recent comments, this is not a virus, and will not delete any files from your computer. In fact, ophCrack, the software we're gonna use is a very popular password cracker. Google it or Wikipedia it if you don't believe me.

This works for WINDOWS ONLY

This will crack all windows passwords up to 14 digits on a computer.
You need physical access to the computer.
You don't need to be logged in (that's what this is for).
It will tell you all user names and passwords on the computer.

Step 1: Get the Resource

1. Go here:

2. Download the latest version of ophcrack live cd. To crack passwords on an XP computer select 'ophcrack XP LiveCD'. To crack passwords on a VISTA computer select 'ophcrack VISTA LiveCD'.

3.The software you download will be a CD image (.iso format). If you try opening this on a computer with a CD-Writer and CD-Writing Software (eg. Nero, Roxio, Record Now, or whatever you have) it will write that file to a CD.
So, make the CD

Step 2: Crack

1. Make sure the computer you intend to crack is off.

2. Turn on, and instantly pop in the CD you just created.

3. By this time, windows might have started loading. So, turn off computer by holding down power button and then turn on again. What you want to do is boot from the CD. This can be done in two ways:
a. Often pressing one of the function keys (depending on manufacturer) takes you into the BIOS setup (the first splash screen that pops up when you turn on your computer should tell you which one: often F2, F11 or F12.) There, you should look around until you find where you can change the boot order (this differs from company to company depending on your computer brand). Change the boot order, so the computer first boots from CD then from Hard Disk.
b. There is often another function key (again depending on manufacturer) which enters you into the boot selection menu where you can select where to boot from. Hit boot from CD.

4. Watch as the CD loads. It will load a temporary version of linux on to the ram, dump all user names in a box and start processing. This software can only crack passwords up to 14 digits. As it deciphers the passwords, it will decipher each password in two blocks of 7 characters each, and then show you the whole password as a combination of those two under the column labeled 'net password'.

5. Vola! In about 5-10 minutes you have all the user names and passwords on that computer.

Why is this under &quot;Props&quot;?
I have tried about 7 of these instructables to go around or reset admin. password and NONE OF THEM work.
ive tried at least 15 of them already and its just like you.&nbsp; NONE OF THEM WORK!!!!<br />
try this program called password-nuker, it resets your SAM file on boot
try my instructable. you don't need any software, just an account on the computer or the computer's network. <a href="https://www.instructables.com/id/how-to-change-windows-passwords-without-logging-on/">https://www.instructables.com/id/how-to-change-windows-passwords-without-logging-on/</a><br/>
i read your instructable first of all the account needs to be an administrator also it dose not work for vista i dont really like it (no offence to you what so ever)
boom-man, the account does NOT need to be an administrator (at least not on the computers i've tried, i have no clue where you've tried) i never said it would work for vista, it says WINDOWS XP in there, just read it carefully. i really don't care that much whether you like it or not, any feedback is good feedback.
try harder, but you're right, most of them only work when you're already admin... This will work (if bootCD isn't locked down in bios) mine will work too I haven't seen other methods on here
hello! nice to have this tool,&nbsp; do you know if it works on windows 7?<br />
no, i do not know any thing about hacking.
AVG says this is an unwanted risky file. It did not load to CD but installed on download computer. This is a bad file to try to use.
and you must have downloaded the executable file. if you want to burn it to a disc you need the iso.
Hello again A.C.E. lol.
&nbsp;Hello again spartan 2209....<br /> <br /> &nbsp;&nbsp;I'm sorry, i actually have no idea who you are..<br /> <br /> &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Everyone was doing it.<br />
Haha funny thing is I've seen you on other instructables many times :P
&nbsp;Yeah i get that =D<br /> <br /> I like this community<br />
of coarse it says its risky! its a password cracker stupid<br />
Technically, every anti-virus scanner I use say something like this, &quot; Warning! Virus PSW.PSWdump has been found&quot; or something like that. <br />
It goes like this, PSW.PSWDump.at (Unclassified Threat)<br />
Wow, are you forgetting the TINY detail that you have to be an administrator to download and install. Good try though.
I had my doubts as to if this would actually work, but my first comment turned around and bit me in the arse and i was totally amazed that it worked, but seriously it went to my head a little bit and i kinda went crazy(me and friend) at school with this. Found Head Admins PW All head teachers PW everyones, pretty cool if you ask me.
RAINBOW FILES PEOPLE!!!!! RAINBOW FILES!!!!<br/>look em up, make em, USE EM!!! u can crack a 14 number and letter password in aprox 2mins max<br/><br/>He he he he, i got 125gig of tables, i can crack nt lm passwords number/letter/symbol at a 96% hit rate :) **evil laugh** ok very serious<br/><br/>here are some helpful things to follow<br/>LOOK UP<br/>LEARN<br/>LOOK UP SUM MORE JUST TO BE SURE<br/>LEARN WHAT YOU NEED TO<br/>AND USE UR KNOWLEDGE IT CAN GET YOU PLACES!!!! money tooo<br/>
If I have used pwdump to get a list of usernames and passwords, how do I crack the hashes
<strong>1st</strong> step learn about rainbow files, learn what your variables could be, or your possible variables could be<br/><strong>2nd</strong> make rainbow files<br/><strong>3rd</strong> download cain&amp;able or another program thats similar. and be on your way<br/><strong>4th</strong> step if your lazy and don't care about time, use a bruteforcer <br/><br/>IM SERIOUSLY NOT GOING TO EXPLAIN TO YOU HOW IT WORKS!!!! WASTING MY TIME!!! ITS SIMPLE! USE WIKIPEDIA OR WHAT EVER!!!!!!!!!!!!!!!!! etc<br/>
"2nd make rainbow files" Have you ever created rainbow tables? Do you know how cpu intensive and time consuming this is? Especially if you need a full character set table generated. Not to mention if you need more than 8 characters. You'll need a 100 GPUs running about 2 years to generate a highly successful and relaible rainbow table.
uselesss, my computer file is 100 letters randomly typed and now remembered by me i remember the whole thing!!!!YOu cann't crack that in less than 10 hours i bet
i know how to generate new sam files. if cracking doesn't work. ill just replace the sam file leaving no passwords
i did a 512 - bit encryption and i made it so it is impossible to delete unless you fry the cpu or something
haha nah it dusnt work that way, the sam file contains info about the pc including specs, keys, passwords etc etc. as long as i got the cd key i can replace the sam file. jsut gota detect specs, enter product key and its ready to go lm and ntlm encryptions don't phase me anymore.
i put it into an encryption folder
